Looking at DR for golems, demons, and Elementals of around our levels, they have between 5 and 10 DR, and each attack I do will be doing maybe 1d10 + 11 before sneak attack (which doesn't work on golems and elementals), which puts the damage through DR10 at somewhere between 2 and 11 with each attack, if all hit (which rarely happens), I get between 10 and 55 damage, where as with an Elder Mountain Hammer, I do 1d10 + 11 +6d6, bypassing DR and hardness, which gives me a damage range of 18-57, and that is one attack at max bonus, rather than one at max, three at -2, and one at -5, not even going to try with the bite, 1d4+1 won't get past 10DR no matter how you slice it.
I think I will keep some stone dragon maneuvers known, but not have them in a standard loadout, load as many as I have if I see a battlefield full of golems or something.
